256色模式下图形图像处理系统中对不规则区域的处理

256色模式下图形图像处理系统中对不规则区域的处理 PROCESSION OF IRREGULAR REGION IN GRAPH IMAGE PROCESSING SYSTEM UNDER 256-COLOR MODE 伊君 1 first-author 陈淑珍 1 孙晓安 1 武汉大学电子信息学学院 武汉大学电子信息学学院 College of Electronic Information,Wuhan University College of Electronic Information,Wuhan University 概述了图形图像处理系统中关于不规则区域的基本算法，包括：区域填充，边界跟踪，边界标志，几何处理，区域分割等等．并且，根据２５６色模式的特殊性，对传统的算法做了有针对性的改进，加快了处理速度，使其更适合于电影电视字幕、动画卡通人物等不规则图形图像区域．同时还给出了改进算法的程序设计的技巧． Algorithms about irregular region procession in graph image processing system under 256-color mode are discussed. Aiming at the peculiarity of 256-color mode, improvements that basing upon the traditional algorithms including region filling,border following, edge flag,geometrical processing and region dividing are presented.Some basic skills on programming are also available. 区域填充 边界跟踪 边界标志 几何处理 区域分割 256色模式 color mode region filling border following edge flag geometrical processing region dividing TP391.41 1995-03-01 2021-04-01 3
